Description

[Technical Field]

[0001] The present invention relates to an external preparation composition. [Background technology]

[0002] Liquid topical skin preparations and patches containing medicinal ingredients such as anti-inflammatory and analgesic ingredients, bactericidal and disinfectant ingredients are known. However, existing liquid topical skin preparations have problems such as being easily rubbed off by clothing after application to the skin, making it difficult to continuously release the medicinal ingredients to the skin. Patches containing medicinal ingredients also have difficulty in continuously releasing the medicinal ingredients to the skin if they do not easily conform to the skin and are easily peeled off. On the other hand, patches that are highly adhesive to the skin also have the problem of placing a heavy burden on the skin when peeled off. Patches also have practical use issues such as being prone to rashes and having an unsightly appearance when applied to the skin.

[0003] Therefore, film-forming preparations that can continuously release medicinal ingredients onto the skin have been studied. Film-forming preparations can form a film when applied to the skin, so they are less likely to rub off than liquid topical skin preparations. They are also preferred in that they are not noticeable when applied to the skin like patches and cause less stress on the skin when removed.

[0004] For example, Patent Document 1 proposes an adhesive solid formulation for skin delivery of drugs, which comprises a drug; a solvent excipient, which comprises a volatile solvent system that comprises a volatile solvent and a non-volatile solvent system that comprises a non-volatile solvent; and a solidifying agent; and has viscosity suitable for application and adhesion to skin surface before the evaporation of the volatile solvent system, and the formulation applied to the skin surface forms a solidified layer after at least partial evaporation of the volatile solvent system, and the drug continues to be delivered to the skin after the volatile solvent system has at least substantially evaporated, and there are at least two volatile solvents, two non-volatile solvents, or two solidifying agents.It is stated that this formulation can provide sustained drug delivery for a long time, is not vulnerable to unintentional removal by contact with clothing, other objects, or people during the duration of application, can be applied to the skin area that follows stretching and expansion without causing unpleasant or poor contact with the skin, and can be easily removed after application and use.

[0005] Patent Document 2 proposes a composition for transdermal administration of a physiologically active agent, which comprises an ethyl acrylate / methyl methacrylate copolymer, ethanol, isopropanol or a mixture thereof, water, and at least one physiologically active agent. The composition is described as a film-forming composition that rapidly forms a non-sticky, durable, and very soft film. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Special Publication No. 2009-519956 [Patent Document 2] Special Publication No. 2014-515365 Summary of the Invention [Problem to be solved by the invention]

[0007] However, even in the techniques disclosed in Patent Documents 1 and 2, there is still room for improvement in the sustained release of drugs, physiologically active agents, etc. into the skin. In addition, improvements in the practical performance of topical compositions, such as quick drying after application to the skin and appearance, are also desired. The present invention relates to an external preparation composition that can sustainably release a medicinal ingredient onto the skin, has good film-forming properties, is easy to apply to the skin, dries quickly, and has an effect of suppressing stickiness and a feeling of tightness in the formed film, and is also excellent in appearance and durability of the film. [Means for solving the problem]

[0008] The present inventors have found that an external preparation composition containing a medicinal ingredient, a water-insoluble polymer, and a predetermined solvent component and having a predetermined viscosity can solve the above problems. That is, the present invention relates to the following. [1] A topical composition containing (A) a medicinal ingredient, (B) a water-insoluble polymer, (C) a non-volatile base, (D) a volatile solvent, and (E) water, and having a viscosity at 25°C of 1.0 mPa·s or more and 10,000 mPa·s or less. [2] A lotion, gel, ointment, cream, or foam formulation comprising the topical composition according to [1] above. [3] An aerosol formulation or pump spray formulation using the topical composition described in [1] above. [4] A method for using an external preparation composition, comprising the steps of applying to the skin an external preparation composition containing (A) a medicinal ingredient, (B) a water-insoluble polymer, (C) a non-volatile base, (D) a volatile solvent, and (E) water, and having a viscosity at 25°C of 1.0 mPa·s or more and 10,000 mPa·s or less, and then drying the composition. [5] A method for producing a coating, comprising the step of applying the topical composition described in [1] above to the skin by directly applying or spraying it. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide an external preparation composition that can sustainably release a medicinal ingredient onto the skin, has good film-forming properties, is easily applied to the skin, dries quickly, and has the effect of suppressing stickiness and a feeling of tightness in the formed film, and is excellent in appearance and durability of the film; a preparation using the same; a method for using the external preparation composition; and a method for producing the film. DETAILED DESCRIPTION OF THE INVENTION

[0010] [External preparation composition] The present invention relates to a topical composition containing (A) a medicinal ingredient, (B) a water-insoluble polymer, (C) a non-volatile base, (D) a volatile solvent, and (E) water, and having a viscosity of 1.0 mPa s or more and 10,000 mPa s or less at 25° C. Hereinafter, this composition will also be referred to as the "composition of the present invention" as appropriate.

[0011] <Definition> As used herein, the term "external preparation composition" refers to a composition that is primarily applied to the skin surface. As used herein, the term "water-insoluble polymer" refers to a polymer that has the property that, when 1 g of the polymer is immersed in 10 g of ion-exchanged water under an environment of 23°C and 1 atmosphere, more than 0.5 g of the immersed polymer does not dissolve after 24 hours. As used herein, the term "non-volatile base" refers to a base that is liquid at 70°C and exhibits a mass loss of less than 1% after 1 g of the base is spread on a 48 mm diameter glass petri dish and left at 25°C and atmospheric pressure for 24 hours. "Volatile solvent" means that 1 g of the solvent is spread on a glass petri dish with a diameter of 48 mm, and after being left at 25°C and normal pressure for 24 hours, the mass loss rate is 1% or more, the solvent is liquid at 25°C, and the solvent contains components other than water. In this specification, the resistance of the coating to sweat, humidity, etc. (moisture resistance) and the resistance of the coating to being rubbed off (abrasion resistance) are collectively referred to as "durability of the coating."

[0012] The composition of the present invention contains component (A): a medicinal ingredient, component (B): a water-insoluble polymer, component (C): a non-volatile base, component (D): a volatile base, and component (E): water, but component (A) is a component that is not contained in any of the other components (B), (C), and (D), and component (B) is a component that is not contained in any of components (C) and (D).

[0013] The composition of the present invention, having the above-mentioned constitution, can sustainably release the medicinal ingredient to the skin, has good film-forming properties, is easy to apply to the skin, dries quickly, and has an effect of suppressing stickiness and a feeling of tightness of the formed film, and has excellent appearance and durability of the film. The reasons for this are not clear, but are thought to be as follows. The composition of the present invention is a film-forming composition that contains, as film-forming components, a water-insoluble polymer as component (B) and a non-volatile base as component (C). When the composition of the present invention is applied to the skin and then dried, components (D) and (E) volatilize, forming a film containing components (A) to (C). Here, when a highly crystalline component such as felbinac, which will be described later, is used as the medicinal component (A), if the compatibility between component (A) and the coating is low, component (A) is likely to crystallize in the coating, resulting in a decrease in sustained release to the skin. However, if the compatibility between component (A) and the coating is too high, component (A) is likely to be taken up into the coating, making it difficult to sustainably release it to the skin. When a water-insoluble polymer, component (B), is used as a film-forming component, the compatibility between the coating and component (A) may become excessively high or low, possibly resulting in a decrease in the sustained release of component (A). In the composition of the present invention, the use of component (C) is thought to reduce the compatibility between the coating and component (A) when the compatibility between the coating and component (A) is excessively high, or to improve the compatibility when the compatibility between the coating and component (A) is low, thereby suppressing the crystallization of component (A), thereby improving the sustained release of component (A). Furthermore, because component (B) is water-insoluble, it can form a highly hydrophobic coating, which makes it difficult for the coating to rub off due to sweat, humidity, etc. after application to the skin, enabling the sustained release of the medicinal ingredient into the skin. Furthermore, the synergistic effect of components (B) and (C) is believed to result in a composition that is easy to apply to the skin, dries quickly, is free from stickiness and tightness, has a good appearance, and is capable of forming a coating that is difficult to rub off after application to the skin and has good durability. It is believed that component (D) contributes to improving the composition's application properties, quick-drying properties, storage stability, etc., and component (E) contributes to improving the composition's storage stability. Furthermore, since the composition of the present invention contains components (D) and (E) and has a viscosity within the specified range, the composition becomes more compatible with the skin, achieving both film-forming properties and film durability, as well as application properties and quick-drying properties, and as a result, it is believed that component (A) can be effectively and sustainedly released onto the skin.

[0025] The component (A) can be one or more of the above-mentioned medicinal components. Among the above, from the viewpoint of being an external preparation composition to be used on exposed and flexed parts of the skin, component (A) preferably contains one or more selected from the group consisting of anti-inflammatory and analgesic components, local stimulating components, blood circulation promoting components, antihistamine components, and herbal ingredients, and more preferably contains one or more selected from the group consisting of anti-inflammatory and analgesic components and local stimulating components.

Also, from the same viewpoint, it is preferably 35.00 or less, more preferably 27.00 or less, even more preferably 24.00 or less, and even more preferably 22.00 or less. The SP value of component (A) is preferably 15.00 or more and 35.00 or less, more preferably 18.00 or more and 27.00 or less, even more preferably 19.00 or more and 24.00 or less, and even more preferably 19.50 or more and 22.00 or less.

[0027] The SP value can be calculated using solubility parameter calculation software (Hansen Solubility Parameters in Practice 4th Edition 4.1.03).

Specifically, the SP value δ is calculated using the following formula: δ=(δD 2 +δP 2 +δH 2 ) 1 / 2

For example, if a mixture of two components, component 1 and component 2, is called "mixture X," and the Hansen solubility parameters of components 1 and 2 that make up mixture X are [δD1, δP1, δH1] and [δD2, δP2, δH2], respectively, and the volume ratio of components 1 and 2 is V1:V2, then the dispersion term δDm, polar term δPm, and hydrogen bonding term δHm of mixture X can be expressed by the following equations. Note that in the case of polymers, the specific gravity was calculated as 1.0. δDm=(V1×δD1+V2×δD2) / (V1+V2) δPm=(V1×δP1+V2×δP2) / (V1+V2) δHm=(V1×δH1+V2×δH2) / (V1+V2) The SP value Δx of the mixture X is calculated using the following formula: δx=(δDm 2 +δPm 2 +δHm 2 ) 1 / 2

[0029] The composition of the present invention, even when a highly crystalline component (A) is used, can suppress crystallization of the component (A) in the coating, enhance sustained release onto the skin, and improve the storage stability of the composition. From the viewpoint of the usefulness of this effect, it is preferable that the component (A) is one or more crystalline active ingredients selected from the group consisting of glycol salicylate, loxoprofen sodium, felbinac, l-menthol, and vanillylamide nonylate. However, the composition of the present invention can also form a coating with high sustained release onto the skin when an amorphous component (A) is used.

[0075] <Dosage form, etc.> The topical composition of the present invention is preferably used as a topical composition for skin. The topical preparation composition of the present invention may be in any dosage form as long as it has a viscosity within the above range and is applicable to the skin. Examples include lotion preparations, gel preparations, ointment preparations, cream preparations, and foam preparations comprising the topical preparation composition of the present invention; and aerosol preparations or pump spray preparations using the topical preparation composition of the present invention. Examples of foam preparations include preparations in which the topical preparation composition of the present invention is filled into a pump former or the like and discharged in the form of foam. The compositions of the present invention can also be electrostatically sprayed onto the skin using an electrostatic spray device, which is described below.

[0076] The aerosol formulation contains the topical composition and a propellant. The aerosol formulation using the topical composition of the present invention can provide a cooling sensation or the like by spraying the composition onto the skin. In the aerosol formulation, the topical composition used as an aerosol concentrate and its preferred embodiments are the same as those described above. That is, the contents and viscosity of components (A) to (E) in the aerosol concentrate are preferably within the above-mentioned ranges. Propellants used in aerosol formulations include liquefied petroleum gas (LPG), which is ethane, propane, normal butane, isobutane, isopentane, and mixtures thereof; ethers such as dimethyl ether; compressed gases such as nitrogen and carbon dioxide; and the like, and one or more of these can be used.

[0077] In the aerosol formulation, the ratio of the mass of the topical composition (aerosol concentrate) to the propellant is not particularly limited as long as it is possible to spray the topical composition onto the skin. From the viewpoint of aerosol performance and the stability of component (A), however, the mass ratio of the topical composition to the propellant is preferably in the range of 1:0.01 to 1:10, more preferably 1:0.05 to 1:7.5.

[0078] Examples of aerosol containers used for aerosol formulations include known pressure-resistant containers made of metal, plastic, etc., as well as double-structure containers in which an inner bag is housed inside a pressure-resistant container. In double-structure containers, it is preferred that the inner bag is filled with the topical preparation composition, which is an aerosol concentrate, and that the space between the pressure-resistant container and the inner bag is filled with a propellant.

[0079] The method for preparing the aerosol formulation is not particularly limited. For example, the aerosol formulation can be prepared by filling the aerosol container with the topical composition as an aerosol concentrate, attaching a valve, and then filling the propellant through the valve.

[0080] The pump spray formulation is a formulation in which the topical composition of the present invention is filled into a pump spray container for use.

[0081] [How to use] The present invention also provides a method for using the topical composition, which comprises the steps of applying the topical composition to the skin and then drying it. According to the method of the present invention, by applying the topical preparation composition to the skin and then drying it, a coating containing the active ingredient, component (A), can be formed on the skin surface. The coating has excellent moisture resistance and abrasion resistance, and is highly capable of sustained release of component (A) to the skin, allowing component (A) to be sustainedly released into the skin. Hereinafter, the process of applying the topical preparation composition to the skin and then drying it will also be referred to as the "coating formation process."

[0082] The method of applying the topical composition to the skin can be appropriately selected depending on the formulation of the topical composition, and examples include application by coating, casting, spraying, etc. Among these, application by coating or spraying is preferred. After application of the topical composition, component (D) volatilizes when the composition is dried by natural drying or the like, and a coating containing components (A) to (C) is formed on the skin surface.

[0083] In the method of the present invention, when the topical composition is applied by direct application to the skin, the topical composition can be applied by hand or using an applicator such as a metal roller, a plastic roller, a sponge-like porous body, or a brush. In the method of the present invention, when the topical composition is applied to the skin by spraying, the method of spraying the composition can be a method using an aerosol, a pump spray, or an electrostatic spray device. For aerosol and pump spray, the topical composition can be used as a stock solution to prepare the aerosol formulation or pump spray formulation, and the topical composition can be sprayed onto the skin using the formulation. Specifically, the electrostatic spray device comprises a storage section capable of storing the topical preparation composition, a nozzle for ejecting the topical preparation composition, a power source for applying a voltage to the nozzle, and means for delivering the topical preparation composition from the storage section to the nozzle. One embodiment of the electrostatic spray device is a handy electrostatic spray device that is sized to be held in one hand. As the electrostatic spray device, those exemplified in International Publication No. 2018 / 194140, etc. can be used.

[0084] The site to which the topical composition is applied is not particularly limited, but is preferably the skin surface of a body part, more preferably the skin surface of the hands, arms, feet, legs, or trunk.

[0085] The amount of the topical composition to be applied to the skin is not particularly limited, but from the viewpoint of sufficiently sustained release of component (A) onto the skin, it is preferably 0.5 μL / cm 2 More preferably, 1 μL / cm 2 More preferably, 3 μL / cm 2 In addition, from the viewpoint of the appearance (transparency) of the formed coating, it is preferable to use 100 μL / cm 2 or less, more preferably 50 μL / cm 2 The following is the result.

[0086] [Coating manufacturing method] The present invention also provides a method for producing a coating, which comprises the step of applying the topical composition to the skin by directly applying or spraying it onto the skin. When the topical composition is applied by direct application to the skin, the topical composition can be applied by hand or with an applicator such as a metal roller, as described above. When the topical composition is applied by spraying it directly onto the skin, the method for spraying the composition includes the use of an aerosol, pump spray, or electrostatic spray device.

[0087] An embodiment of a method for producing a coating when applying an external preparation composition to the skin by electrostatic spraying using an external preparation composition and an electrostatic spray device will be described below. First, the storage compartment of the handy electrostatic spray device is filled with the topical composition, and the user, i.e., the person who forms a coating on the application site on the skin by electrostatic spray, holds the device in his / her hand and points one end of the device, where the nozzle is located, toward the application site where electrostatic spraying will be performed. Under these conditions, the electrostatic spraying method can be performed by turning on the electrostatic spray device. When the device is turned on, an electric field is generated between the nozzle and the skin, a positive high voltage is applied to the nozzle, and the skin becomes the negative electrode. When an electric field is generated between the nozzle and the skin, the topical composition at the tip of the nozzle is polarized by electrostatic induction, forming a cone-shaped tip. Charged droplets of the topical composition are ejected from the tip of the cone into the air along the electric field toward the skin. As the volatile solvent (component (D)) evaporates from the charged topical composition ejected into space, the charge density on the surface of the topical composition becomes excessive, causing the particles to repeatedly break down into small particles due to Coulomb repulsion, spreading into space and reaching the skin. In this case, by appropriately adjusting the viscosity of the topical composition, the amount of volatile solvent, the type and amount of polymer, the flow rate, the voltage, and the like, the sprayed composition can be made to reach the application site in the form of droplets. Preferably, component (D) is evaporated from the droplets while being discharged into the space, and component (B), the main film-forming component, is solidified while being stretched and deformed by the potential difference to form fibers, which can then be deposited on the application site, forming a porous film consisting of the fiber deposit on the surface of the application site.

The longest time during which the film remained was scored according to the following criteria. 5: 8 hours later, 4: 4 hours later, 3: 1 hour later, 2: 30 minutes later, 1: 10 minutes later

[0097] (Storage stability) 10 g of each topical composition was placed in a screw tube No. 4 (manufactured by Maruemu Co., Ltd.), the tube was capped, and the appearance, odor, viscosity, and pH were checked for changes over time after storage in a thermostatic chamber at 0°C and 40°C for one week, and the results were evaluated according to the following criteria. A: No change in appearance, smell, viscosity, or pH B: There is a slight change in one or more of the following: appearance, smell, viscosity, or pH C: There is a change in any one of appearance, smell, viscosity, or pH. D: Changes in two or more of appearance, odor, viscosity, and pH

[0098] (Film forming property) The topical composition of each example was applied to the surface of artificial leather ("Suprare" manufactured by Ideatex Japan Co., Ltd.) at a dose of 6 μL / cm 2 The topical composition was applied to the skin and then dried for 1 hour on a hot plate ("Ceramic Hot Plate" manufactured by AS ONE Corporation) set to 32°C. The applied area of ​​the topical composition was visually observed, and the film-forming ability was judged according to the following criteria. A score of 3 or higher was considered to be acceptable. 5: A uniform and sufficiently thick coating is formed; 4: A uniform and thick coating is formed; 3: A thin but uniform coating is formed; 2: A coating is present but is uneven; 1: The presence of a coating cannot be confirmed.

[0099] (Amount of medicinal ingredients permeated through the skin) The external preparation composition of each example was applied to the surface (one side) of the stratum corneum of a pig's ear placed in a Franz diffusion cell (manufactured by PermeGear) at 6 μL / cm 2 Cumulative skin permeation of active ingredients after 8 hours (μg / cm 2 ) was measured. The higher the value, the higher the permeability of the active ingredient into the skin.
